Shirts: What Material Should I Buy? A Technical Fabric and Fit Guide for Everyday Dressing

Shirts are the cornerstone of modern wardrobes—worn for work, weekends, events, and everything in between. But one of the most overlooked decisions when shopping for shirts is material. From crisp cotton poplin to relaxed linen, stretch blends to structured twill, your choice of fabric affects comfort, fit, durability, breathability, and how the shirt moves with you.

In this technical guide, we break down the best shirt materials, what each one is suited for, how they affect sizing and wear, and how to avoid costly fit mistakes—especially when buying online. With over 1,500 brands supported, Tellar.co.uk is the UK’s leading free sizing tool, helping you get the perfect shirt size first time.

Why Shirt Material Matters

Shirt sizing can be deceptive—a cotton Oxford in size M may fit entirely differently than a rayon blend in the same size. Tellar.co.uk takes material and brand-specific sizing into account for precision fitting.

1. Cotton Poplin: The Crisp Classic

Technical Specs:

• Tightly woven cotton with a smooth, fine texture

• Lightweight, crisp, and cool against the skin

Pros:

• Holds shape well

• Less flexible (no stretch) unless blended

Fit Tip:

Poplin is non-stretch and unforgiving if tight at the chest or shoulders. Use Tellar.co.uk to ensure your neck size and shoulder width match brand blocks, especially for slim fits.

4. Twill Weave: Smooth, Draping, and Wrinkle-Resistant

Common Shirt Buying Mistakes to Avoid

❌ Ignoring fibre content—poplin, twill and Oxford cotton behave very differently

❌ Choosing “slim fit” without verifying shoulder and chest size

❌ Overlooking collar types (spread vs cutaway vs button-down)

❌ Not accounting for post-wash shrinkage

❌ Buying off tag size alone—especially in stretch blends or linen

The easiest way to avoid these pitfalls? Tellar.co.uk matches your exact measurements to shirt fits by brand, fabric type, and even cut.

Shirt Fit Fundamentals: Why Size Varies by Material

• Cotton poplin has zero stretch—tight fits can feel restrictive

• Linen expands and contracts, especially in warm weather

• Blends with elastane are more forgiving, but can mislead on size

• Oxford and twill shrink less but drape differently
